Detecting gene flow from GM crops
The likelihood of transgene movement into wild relatives of cultivated crops varies vary dramatically with geography. From the perspective of the UK, crops such as maize lack any close relatives and so effectively cannot act as a source for transgene recruitment into wild plant species. At the other extreme, forage grasses such as Lolium perenne are wind pollinated and have abundant wild popula...
متن کاملGene flow from glyphosate-resistant crops.
Gene flow from transgenic glyphosate-resistant crops can result in the adventitious presence of the transgene, which may negatively impact markets. Gene flow can also produce glyphosate-resistant plants that may interfere with weed management systems. The objective of this article is to review the gene flow literature as it pertains to glyphosate-resistant crops. Gene flow is a natural phenomen...
متن کاملHerbicide Resistant Weeds and Crops
Modern herbicidal weed control often exploits physiological differences among plants and takes advantage of herbicide tolerance or resistance in crop plants to bring about the selective removal of susceptible weeds. The Weed Science Society of America defines herbicide tolerance as “the inherent ability of a plant to survive and reproduce after herbicide treatment” which suggests that herbicide...
متن کاملFrom weeds to crops: genetic analysis of root development in cereals.
Root development of Arabidopsis, Zea mays (maize) and Oryza sativa (rice) differs in both overall architecture and the anatomy of individual roots. In maize and rice, the post-embryonic shoot-borne root system becomes the major backbone of the root stock; in Arabidopsis, the embryonic root system formed by a simple primary root and its lateral roots remains dominant. Recently, several specific ...
متن کاملGlyphosate - Resistant Crops and Weeds : Now and in the Future
The adoption of transgenic crops (also called GMOs and biotech crops) worldwide has been rapid and impressive, reaching 120 million ha in 2008, and continues to grow at a steady pace (James, 2008). Approximately 80% of the total area devoted to these crops has been planted with herbicide-resistant crops, virtually all being glyphosate-resistant (GR) crops. Thus, a single genetic trait—glyphosat...
